We've set a goal of recruiting 200 ongoing supporters to donate $15 or more each month in 2025. Please help us reach this goal and make next year's flora even better:
Solidagopatula Muhlenberg ex Willdenow. Subgenus:Pleiactila. Section:Argutae. Subsection:Patulae. Northern Roughleaf Goldenrod. Phen: Aug-Sep (-Oct). Hab: Bogs, seepages over mafic rocks, grassy balds (as Whitetop Mountain). Dist: NH, VT, NY, s. ON, MI and WI south to w. VA, w. NC, nc. GA, c. TN, w. TN, and se. MO. Coastal Plain records (except northwards, in DE, NJ, and NY) represent misidentifications of S. salicina.
ID notes:The broad basal leaves, saturated wetland habitat, and finely but definitely scabrous upper leaf surface are distinctive.
Origin/Endemic status: Native
Taxonomy Comments: Semple, Tong, & Pastolero (2012) have clarified the taxonomy, distribution, and nomenclature of this and S. salicina.
